Senate rejects limiting Trump's military authority on Iran

• The resolution, offered by Sen. Tim Kaine (D-Va.), was rejected 47-53. One Democrat — John Fetterman (Pa.) — voted "no," and one Republican — Rand Paul (Ky.) — voted "yes."
• Many Democrats, and even some Republicans, have argued that the White House was required to seek consent from Congress before green-lighting last weekend's strike.
• But the White House received backup from Republican leadership on the Hill, with Speaker Mike Johnson (R-La.) going so far as to suggest the War Powers Act is unconstitutional.

The big picture: The Iran strike reignited an old tug-of-war between the executive branch and Congress over war powers.

• Trump twice vetoed resolutions related to the War Powers Act in his first term, including one aimed at curtailing his powers to strike Iran.
• Congress also confronted the question when President Obama authorized air strikes on Libya in 2011.

Zoom in: A pair of briefings in the Senate and House on Thursday and Friday did little to satisfy Democrats.

• House Democrats left their Friday morning largely grumbling at what they described as "propaganda" and a "waste of time."
• The sentiment was similar among Democratic senators following their Thursday afternoon session.
